I recently tried add extensions in ExoPlayer like ffmpeg extension to support more audio formats in my app, i followed the extension-ffmpeg Readme.md and i successfully created the library for arm64-v8a, armeabi-v7a, x86 and x86_64 and inside of these folders are libavcodec.so, libavutil.so and libswresample.so, After successfully creating the library i need to build the aar to include it in my app but when i run
cd "${FFMPEG_EXT_PATH}" && \
${NDK_PATH}/ndk-build APP_ABI="armeabi-v7a arm64-v8a x86 x86_64" -j4
i get this error

I'm a newbie to this and i have tried to see some examples of Android.mk for exoplayer ffmpeg extensions but i did no find anything and i'm stuck in this part, i'm still searching for some examples that might help me to successful build the extension ffmpeg aar.
